iFi Go Link

The Go Link It's the missing link in your listening experience.

Firstly, it will allow wired headphones and headsets to connect to digital devices that do not have a 3.5mm headphone output.

Second, even if your device has a headphone jack, the GO Link offers a great sound upgrade. That's because its sophisticated DAC (digital-to-analog converter) and headphone amplifier circuitry are superior to the audio technology contained in smart devices and computers.

At one end of the GO Link There's one USB-C connector, and on the other is the DAC circuit and headphone amplifier, both housed in sturdy but lightweight magnesium alloy cases.

In the middle is a 6cm long flexible cable: this helps with practicality as it allows the DAC/amplifier section to angle towards the listener and reduces strain on the USB port the GO Link is connected to,

At the heart of GO Link is a high-performance, low-power DAC chip from ESS Technology's Saber HiFi series, the ES9219MQ/Q, which benefits from the 32-bit HyperStream III architecture.

This combines with Quad DAC+ and Time Domain Jitter Eliminator technologies, plus our dedicated clock circuit using a specialized crystal oscillator, to deliver ultra-low distortion, excellent clarity and impressive dynamic range.

Rarely implemented high-end features such as adjustable analog gain with DRE (Dynamic Range Enhancement) plus technologies to minimize THD (Total Harmonic Distortion) and crosstalk are possible due to the advanced specification of the DAC chip.

It is also possible to choose from a selection of digital filters through downloadable software.

The cable linking both sections uses silver-plated copper conductors with individual polymer insulation in a 'twisted pair' configuration.

This twist helps optimize inductance and capacitance and also helps with noise rejection. The GO Link sound It is not affected by electromagnetic interference picked up by nearby electrical sources.

Unlike other headphone DACs, the GO Link does not depend on software-based volume controls on connected digital devices. This may negatively affect the audio resolution.

Instead, adjusting the volume on the connected device controls the volume level on the GO's DAC Link , not on your phone, tablet or PC. This hardware-based volume control is another feature that helps deliver the GO's superior sonic performance. Link .

The GO Link's headphone amplifier powers a gold-plated 3.5mm jack, which features our S-Balanced configuration to reduce noise and crosstalk.

It offers a power output of 70 mW at 32 ohms and a maximum voltage output of 2.05 V at 600 ohms. This gives it plenty of oomph to handle the type of headphones and earbuds that are likely to be used with the GO Link and easily outperforms the headphone outputs built into smart devices and computers.
